' Theicontact-strips 6 and 7 are engaged with one another at their free ends by means of the terminal 1() which is preferably integral with contact-strip 6.

The reference character 23 designates a suitable, preferably metallic casing .or housing which may be provided with a hinged cover or door and provided with a suitable lock, if desired. The housing 23 is preferably attached to any convenient portion of the automobile, preferably to the underside 4of theiioor,by means of any well known pletes the circuit through the battery or magneto, the coill and switch, then through conductor 5, contact-strip 6 and contactstrip 7 to ground. y 4

The reference characterB designates a high-tension type of ignition which includes the usual magneto 8, dash-switch 9 and groundlO. 11 represents a conductor leading from the magneto side of dash-switch 9 to the contact-strip 12.

horn circuit is an audible signal, such as'an electric-bell 21. *Both signals may be sounded simultaneously 'if desired. Vhen is only desired to sound the horn 1-8, the switch 56 is turned to break the circuit to the bell 21. lVhen the contact-strips 19'and 2() are open, as shown in Fig. 1, the signals are inoperative, but when contact-strips 19 and 20 are forced into engagementwithvone another the circuit is closed, thus soundingl either or both of the signals 18 and 21.

Adapted to be suitably placed and secured within the housing 23 is the mechanical portion of my invention, which consists or' a suitably perforated top plate 24 and a lower plate 25.v These plates are suitably spaced apart by means of the corner spacing-blocks 26, 27, and 28 and the intermediate spacing blocks 29 and 30. By this arrangement it It is also provided with the stop-pins 34.

A suitable spring member 35 is employed to normally hold theV plunger 31 in the position 'shown in Fig. 1. One end of the spring member 35is secured to the bottom plate 25 While the opposite end is` secured to the plunger 31. 'removably attach to the post 36 the flexible element or cable 37. This cable 37 is in'turn `preferably connected to the emergency brake-lever 38 of an automobile. -The lever 38 and cable 37 move the lunger 31 in one direction and that When being set.
